The diagnostic trouble code (DTC) P2135 for a 2006 Lexus RX 330 refers to an issue with the Throttle/Pedal Position Sensor/Switch 'A'/'B' Voltage Correlation.
So, this can be the throttle pedal sensor on the throttle body this is why many dealers change both at the same time.
I would change the throttle bore first because they have a higher failure rate. Here is how the job is done and please clear the codes when the job is complete. Check out the images (below). Please let us know what happens.
